46 // <synopsis>
47 // This class is a simple class used in the Map<key,value> classes
48 // to manage key/value pairs for maps.
49 // The default constructor is needed for use in containers.
50 // This implies that ALL classes ever used in OrderedPair should
51 // have a default constructor!!!!
52 //
53 // <note>
54 // This should probably be cleaned up in the future and made into a
55 // generally useful class.
